Research: environmental change and migration

How will changing environmental conditions influence the selective pressures on migration?

Migration is essentially an adaptive response to environmental conditions, so as conditions change, the selective pressures on migration also change. This can result in previously migratory species shifting to be non-migratory (and vice versa), which can in turn have consequences for the survival and viability of these species.

We show that for a species of land crab with partial migration, global climate change (based on projections) may reduce the frequency at which individuals migrate, which could have quite a negative impact for this species (Shaw & Kelly 2013).

Can we generalize the ways in which different types of environmental change are expected to influence large-scale movement patterns?

How will the motivation behind migration influence the ability of a species to adapt its movement in response to changing condition?
